Measuring 138 inches long and 1.25 inches wide with a 0.042-inch thickness, this blade fits standard vertical bandsaws used in metal fabrication and production cutting. The variable pitch tooth pattern at 3 to 4 TPI reduces harmonic vibration during the cut, extending blade life and improving surface finish on structural steel, pipe, tube, and solid bar stock. High speed steel teeth are electron-beam welded to a flexible alloy steel back, delivering durability in demanding cut cycles. Licensed HVAC, pipefitting, and fabrication shops will find this blade suitable for a wide range of metal-cutting applications.\u003c\/p\u003e\n\u003cp\u003eThe STARRETT 20649 is part of the Intenss PRO series, designed for variable-pitch metal cutting on vertical bandsaw machines. It is suited for ferrous metals such as structural steel, angle iron, and steel tubing, as well as non-ferrous metals including aluminum, brass, and copper. The raker tooth set and positive rake angle promote aggressive chip clearance and efficient cutting action, making this blade appropriate for production environments where consistent throughput is required. This blade is sold as a single welded loop, ready to install without additional cutting or joining.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable pitch 3 to 4 TPI pattern reduces vibration and noise during cutting\u003c\/li\u003e\n  \u003cli\u003eBi-metal construction with high speed steel teeth bonded to a flexible alloy steel back\u003c\/li\u003e\n  \u003cli\u003eRaker tooth set with positive rake angle for aggressive chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight tooth form optimized for consistent cross-section cuts in metal\u003c\/li\u003e\n  \u003cli\u003eFlexible back type resists fatigue and extends service life on continuous-duty saws\u003c\/li\u003e\n  \u003cli\u003eCompatible with ferrous and non-ferrous metal applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for vertical bandsaw machines accepting a 138-inch blade loop that is 1.25 inches wide.

Disconnect and lock out electrical power to the bandsaw before removing or installing any blade. Verify blade tension and wheel tracking according to the machine manufacturer's specifications before resuming operation. Always wear cut-resistant gloves when handling bandsaw blades, as welded loop edges are sharp.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Length\u003c\/strong\u003e: 138 inches (11 feet 6 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Width\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Thickness\u003c\/strong\u003e: 0.042 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 3 to 4 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Pattern\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Material\u003c\/strong\u003e: Bi-Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Set\u003c\/strong\u003e: Raker\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Form\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Rake Angle\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack Type\u003c\/strong\u003e: Flexible\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Ferrous Metal, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Intenss PRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242112\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20649\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538956943666,"sku":"20649","price":176.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/24200e8ad6f3281f1b5ee27144de562d_262da412-7640-44d1-a99d-3f8646443d74.jpg?v=1785830859","url":"https:\/\/voomisupply.com\/products\/starrett-20649-welded-bandsaw-blade-3-4-tpi-bi-metal","provider":"Voomi Supply","version":"1.0","type":"link"}
